[0006] A skin paste for the wound secretion sampling of being convenient for, including flat layer adhering to skin, internal hollow part rising and bending continuously, the hollow part covers above wound, and wound secretion can flow along the curved channel until the hollow part reaches the state of filling.

[0007] Further, the skin paste is provided with cutting line around for dividing the skin paste.

[0008] Further, the top surface of the hollow part is circular arc shape.

[0009] Further, the flat layer comprises an outer first adhesive layer and a second adhesive layer distributed in the hollow part.

[0010] Further, the flat layer is integrally formed with the hollow part.

[0011] Further, the skin patch further comprises a backing layer for the flat layer to adhere.

[0012] Further, the hollow part is made of silicone.

[0013] Compared with the prior art, the skin patch has the following beneficial technical effects:

[0014] The hollow part in the flat layer of the skin patch can make the wound secretion flow along the channel to fill, avoid the accumulation of exudate, and reduce the risk of infection. The three-dimensional printing process produces a three-dimensional hollow structure on the adhesive layer of the patch film, so that there is a gap between the adhesive layer and the wound surface, and the patch film will not cause pulling on the wound when it is peeled off. In addition, the gap can also achieve the collection of secretion samples by puncturing into the hollow part of the patch film without removing the patch film. The flexible substrate used in the hollow part of the skin patch is transparent silicone material, which is safe, stable, odorless and non-toxic, and is widely used in the medical field. It has certain elasticity and flexibility, and can be pressure cast and shaped, so as to realize the three-dimensional structure design of the patch film. The graphic design takes into account the left and right sides of the human body and the shape of most catheters and wounds, so it has a wider application range than the previous skin patch film.

[0022] The embodiments of the present application will be described in detail below with specific examples. Other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of the present application. The present application can also be implemented or applied in different specific embodiments, and various modifications or changes can be made to the details in the present application based on different views and applications without departing from the spirit of the present application. It should be noted that the drawings provided in the following examples only schematically illustrate the basic concept of the present application, and the following examples and features in the examples can be combined with each other without conflict.

[0023] In the drawings, only the schematic representation is shown, and the representation is only a schematic diagram, not a physical diagram, and should not be understood as a limitation of the present application; in order to better illustrate the embodiments of the present application, some components in the drawings are omitted, enlarged or reduced, and do not represent the actual size of the product; for those skilled in the art, the omission of some well-known structures and their descriptions in the drawings is understandable.

[0024] Referring to Figure 1 The present application provides a skin patch convenient for sampling wound exudates. The skin patch comprises a flat layer 100, a raised and curved continuous hollow portion 200 is arranged inside the flat layer 100, and the hollow portion 200 covers above a skin wound 400. The flat layer 100 is composed of a first adhesive layer 101 on the outside and a second adhesive layer 102 distributed in the hollow portion 200. This structure design can ensure good contact with the skin when the skin patch is attached to the skin, and can also realize the flow guiding function of the wound exudates through the hollow portion 200.

[0025] Referring to Figure 2 The adhesive layer is made of a flexible base material. The design pattern is arranged on the flexible base material by the intaglio printing process, so that the adhesive layer forms a part of the three-dimensional hollow structure, i.e. the hollow portion 200. The top surface of the hollow portion 200 is arc-shaped. This unique shape is conducive to better guiding the wound exudates to flow along the curved channel until the hollow portion 200 reaches the full state, realizing the flow guiding of the liquid and the protection of the wound.

[0026] Referring to Figure 3 The skin patch further comprises a backing layer 500, and the backing layer 500 is laminated with the adhesive layer. Before use, the backing layer needs to be torn off. The function of the backing layer is to protect the adhesion of the adhesive layer, so as to ensure that the skin patch can be firmly attached to the skin when used.

[0027] Referring to Figure 4 and Figure 5In actual use, first, the wound is disinfected, and after the disinfectant dries, the skin patch is pasted. After tearing off the backing layer 500 of the skin patch film, the pasting direction and angle are selected according to the position of the wound and the local skin condition to ensure that the wound is in the three-dimensional space, i.e. in the area covered by the hollow part 200. Then press the adhesive part of the film gently to attach the whole film to the local skin.

[0028] In addition, the skin patch is provided with a cutting line 300 around it for dividing the skin patch. The cutting line 300 facilitates adjustment and operation of the skin patch according to actual needs during use, for example, when special treatment or observation of the wound is needed, the skin patch can be partially cut along the cutting line 300 without affecting the overall pasting effect and flow guiding function.

[0029] Moreover, the hollow part 200 is made of silicone. Silicone has good flexibility, stability and biocompatibility, which can ensure the protection of the wound and will not cause irritation or allergic reaction to the skin. The choice of this material further improves the performance of the skin patch, making it better meet the multifunctional needs of wound protection, observation and nursing, liquid flow guiding, specimen sampling, etc. It breaks through the limitations of the flat mechanism of the past skin patch film, effectively prevents wound infection by reducing the risk of wound being pulled and overflow being soaked. Moreover, the skin patch of the utility model is light and portable, and can be widely used in multiple medical scenes, providing a more convenient and efficient wound care solution for medical staff and patients.
